Clinical Evolution of Preschool Picky Eater Children Receiving Oral Nutritional Supplementation during Six Months: A Prospective Controlled Clinical Trial.

OBJECTIVE: To determine if oral nutritional supplementation of picky eater children has a beneficial effect in addition to nutritional guidance on anthropometric parameters, nutrient intake, appetite, physical activity, and health complications. METHODS: This is a randomized, single-blind, controlled clinical trial that included Brazilian picky eater children aged 24 to 60 months. The individuals were randomized into a control group (CG) (n = 17) and an intervention group (IG) (n = 18), and were followed up in seven meetings for 180 days (baseline plus one meeting every 30 days). The CG received nutritional guidance for food selectivity, while the IG received the same guidance plus oral nutritional supplementation. Anthropometric and nutrient intake assessments were carried out, and appetite, physical activity and health complications were investigated. RESULTS: In the IG, the z-score of weight and height increased significantly over time (p < 0.05), while the body fat percentage (BFP) and BMI z-score remained unchanged. The percentage of inadequate intake of vitamins D, C and folate reduced in the IG over time compared to the CG (p < 0.05). In the IG, the score assigned by parents to the appetite scale increased over time (p < 0.05). There was no difference between the groups in the scores on the physical activity and global health scales, and in the number of health complications. CONCLUSIONS: Picky eater children that were supplemented increased their weight not by gaining fat, but due to an increase in stature, as shown by BMI z-score and BFP, that remained unchanged. Furthermore, they showed a decrease in inadequate micronutrient intake during the intervention. An improvement in appetite was also observed over time, attesting to the benefit of supplementation.

Nutritional status of iodine in pregnant and non-pregnant adolescents assisted at the Family Health Strategy in Vespasiano, MG / Estado nutricional de iodo em adolescentes gestantes e não gestantes assistidas na ESF em Vespasiano, MG

Abstract Objectives: to evaluate the nutritional status of iodine in pregnant adolescents, taking into account the increase in the demand for iodine during pregnancy and the absence of iodization strategies for this population. Methods: cross-sectional study conducted with 62 pregnant and 71 non-pregnant adolescents assisted in primary care. The nutritional status of iodine was determined by urinary samples. The iodine concentration in the consumed culinary salt was also evaluated. For the comparative analyses of categorical variables, the Chi-square test was used and for the continuous variables, the Kruskal-Wallis test, considering a 95% confidence interval (CI) and significance level of 5%. Results: the mean iodine concentration in household salt was 25.1 mg/kg (CI95%= 11.1-67.5 mg/kg), with higher mean content in culinary salt in the group of pregnant women (p<0.028). Regarding the nutritional status of iodine, 71% of pregnant adolescents were deficient and 29% iodine-sufficient, with significant difference when compared to 38% of deficiency and 62% of sufficiency in the control group (p<0.001). Conclusions: there was an iodic deficiency among pregnant adolescents, even in the face of higher concentrations of iode in household salt, exposing a paradox between higher consumption and lower sufficiency in this group. Thus, it is suggested to consider iodine supplementation during pregnancy, seeking to minimize the effects of this deficiency on maternal and child health.

Resumo Objetivos: avaliar o estado nutricional de iodo em adolescentes gestantes, levando-se em consideração o aumento na demanda de iodo na gestação e a ausência de estratégias de iodização para essa população. Métodos: estudo transversal realizado com 62 adolescentes gestantes e 71 não gestantes assistidas na atenção primária. O estado nutricional de iodo foi determinado pela concentração de iodo em amostras urinárias. O teor de iodo no sal culinário também foi avaliado. Para as análises comparativas das variáveis categóricas utilizou-se o teste de qui-quadrado e para as variáveis contínuas o teste Kruskal-Wallis, considerando intervalo de confiança (IC) de 95% e nível de significância de 5%. Resultados: a média da concentração de iodo no sal domiciliar foi de 25,1 mg/kg (IC95%= 11,1-67,5 mg/kg), com maior teor médio no sal culinário de gestantes (p<0,028). Em relação ao estado nutricional de iodo, 71% das adolescentes gestantes mostraram-se deficientes e 29% iodo-suficientes, com diferença significativa quando comparadas aos 38% de deficiência e 62% de suficiência no grupo controle (p<0,001). Conclusões: observou-se deficiência iódica entre adolescentes gestantes, mesmo diante de maiores concentrações de iodo no sal domiciliar, expondo um paradoxo entre maior consumo e menor suficiência neste grupo. Assim, sugere-se considerar a suplementação de iodo na gestação, buscando-se minimizar os efeitos desta carência sobre a saúde maternoinfantil.

Prevalence of childhood anaemia in Brazil: still a serious health problem: a systematic review and meta-analysis.

OBJECTIVE: To estimate the prevalence of anaemia in Brazilian children up to 83·9 months old. DESIGN: Systematic review and meta-analysis, using databases PubMed, Scopus, SciELO, Lilacs, Google Scholar, Periódicos Capes, Arca, Biblioteca Virtual em Saúde, Microsoft Academic Search and Cochrane Library using search terms: anaemia, prevalence, child and Brazil. PROSPERO Registration number: CRD42020208818. SETTING: Cross-sectional, cohort, case-control and intervention studies published between 2007 and 2020 were searched, excluding those who assessed children with an illness or chronic condition. The main outcome was anaemia prevalence. Random effects models based on the inverse variance method were used to estimate pooled prevalence measures. Sensitivity analyses removed studies with high contribution to overall heterogeneity. PARTICIPANTS: From 6790 first screened, 134 eligible studies were included, totalling 46 978 children aged zero to 83·9 months analysed, with adequate regions representativeness. RESULTS: Pooled prevalence of anaemia was 33 % (95 % CI 30, 35). Sensitivity analyses showed that withdrawal of studies that contributed to high heterogeneity did not influence national average prevalence. CONCLUSIONS: Childhood anaemia is still a serious public health problem in Brazil, exposing 33 % of Brazilian children to the anaemia repercussions. The main limitation of the study is the estimation of national prevalence based on local surveys, but a large number of studies were included, with representation in all regions of the country, giving strength to the results. In Brazil, more public policies are needed to promote supplementation, fortification and access to healthy eating to reduce the high level of anaemia among children.

Assessment of pre- and post-operative nutritional status in patients undergoing orthognathic surgery / Avaliação do estado nutricional pré e pós-operatório em pacientes submetidos à cirurgia ortognática

ABSTRACT: Introduction: The maxillofacial procedures for skeletal deformities are characterized by structural-morphological changes derived from unfavorable genetics with diagnosis performed during craniofacial growth. Orthognathic surgery requires a total restriction on chewing for 60 days, leading to loss of body weight in overweight and obese individuals, as well as in well-nourished patients. Objective: Evaluating the pre- and post-operative nutritional status of patients undergoing orthognathic surgery. Material and methods: This is an interventional study. The study group received supplementation with whey protein, L-arginine, L-glutamine, and fatty acid Omega-3, and both groups were assessed in terms of anthropometric and biochemical measurements. The evaluation of soft tissue healing was conducted after surgery. Results: It is possible to infer that the percentage of skeletal muscle mass tends to increase in the intervention group, however, the weight loss was greater (-4.88%). Uric acid increased post-operative in the control group (+37.64%). Conclusion: Oral nutritional supplementation used in the study seems promising for reducing the loss of skeletal muscle mass, but further studies involving a larger number of patients are needed to confirm the results.

RESUMO: Introdução: Os procedimentos maxilofaciais para deformidades esqueléticas são caracterizados por intervenções morfológicas estruturais, necessários por conta de genética desfavorável com diagnóstico feito durante o cresci-mento craniofacial. A cirurgia ortognática requer uma restrição total na mastigação por 60 dias, levando à perda de peso corporal em indivíduos com sobrepeso e obesos, bem como em pacientes bem nutridos. Objetivo: Avaliar o estado nutricional pré e pós-operatório dos pacientes submetidos à cirurgia ortognática. Material e métodos: Trata-se de um estudo de intervenção. O grupo de estudo recebeu suplementação com proteína de soro de leite, L-arginina, L-glutamina e ácido graxo ômega-3 e ambos os grupos foram avaliados em termos de medidas antropo-métricas e bioquímicas. A avaliação da cicatrização de tecidos moles foi realizada após a cirurgia. Resultados: É possível inferir que o percentual de massa muscular esquelética tendeu a aumentar no grupo de intervenção, porém a perda de peso foi maior (-4,88%). O ácido úrico aumentou no pós-operatório no grupo controle (+37,64%). Conclusão: A suplementação nutricional oral utilizada no estudo parece promissora para reduzir a perda de massa muscular esquelética, mas estudos adicionais envolvendo um número maior de pacientes são necessários para confirmar os resultados.

Do all infants need vitamin D supplementation?

A high prevalence of vitamin D deficiency (VDD) in children has been observed worldwide, but there are few studies on the nutritional status of vitamin D (VD) in healthy infants. The main cause of deficiency in healthy children is breastfeeding without supplementation and lack or insufficiency of sun exposure. The aims of this study were to determine serum concentrations of 25(OH)D and verify its association with parathyroid hormone (PTH) concentrations and use of VD supplementation in healthy infants aged ≥ 6 to ≤ 24 months attended at two Primary Health Care Units in Ribeirão Preto city, São Paulo, Brazil. A cross-sectional, observational and analytical study was performed in which serum concentrations of 25(OH)D, PTH, alkaline phosphatase (AP), calcium (Ca), phosphorus (P) and albumin were determined in 155 healthy infants. Information on sun exposure, sociodemographic aspects of mothers and clinical and nutritional characteristics of infants were obtained through interviews with responsible infants's legal representatives. Ten infants (6%) presented deficient 25(OH)D serum concentration (≤20ng/ml) and 46 (30%), insufficient (21 to 29ng/ml). No changes in serum P, Ca and albumin concentrations were detected. Only one infant had an increase in PTH serum concentrations. 35% (55/155) of infants had high AP e 40% (22/55) presented insufficient serum concentrations of 25(OH)D but none presented deficient ones. There was a weak association between serum concentrations of 25(OH)D and PTH and an association between serum concentrations of 25(OH)D and P when adjusted for sex, age and BMI. There were no associations between inadequate serum concentrations of 25(OH)D (deficient ou insufficient), sun exposure and VD supplementation. This study found a low prevalence of deficient 25(OH)D serum concentration and high prevalence of insufficient ones which was not associated with changes in serum PTH, AP, P, Ca and albumin concentrations, VD supplementation and the formula volume intake.
